UART Port [J6]

Do not provide power to DynaWave through both the USB Device Port and UART Port at
the same time. Doing so could present a safety hazard and / or permanently damage the
device and connected equipment. Solution designs should include safeguards against
accidental double connections throughout the product's lifecycle.
The UART port J6 can be used to provide power and bidirectional TTL-level serial communication with
a UART-capable host, which is generally a custom board designed specifically for the solution. The
UART port can also be used to provide earth ground in cases where earth ground is not available to the
USB Device Port [J3] (see section 2.3 Grounding / ESD Protection). The port connector is a JST
B10B-ZR-SM4-TF header designed to mate with a JST ZHR-10 connector or equivalent. Table 2-1
provides the port's pinout definitions, and Figure 2-2 shows the physical location of pin 1.
